,Y lApplicati'onflied November Thisinventi'on relates to an, improvementyin gasl burners orfurnaceaf melting pots, vandthelike.y ,Y g' An objectof `this invent-ion is to vprovide the shell carrying lthev 4burnernozzlewith a number of rings for increasing the height of the shell forthe purpose Vofv directing. the

iiame and products of combustion iniclose proximity to the article beingheated. The burners are vemployed in heating various shaped articles andare generally attached to a manifold vso that a great number of burnlers may be used and arranged about the surface of the receptacle to beheated and thereby 1 5 subject the contents of the receptacle to anintense heat from a number of different points. Some of thesereceptacles, re boxes or melting pots, have concave or similarly shapedbottoms, and where the shells are all of the same height, only thelowermost portion of such receptacles receive an intense heat, and whilethe side walls receive heat l Ait is not as intense as it is at thelowermost vportion of the receptacle. To overcome this objection thisinvention provides a number of rings on the shelll of each burner,whereby the rings may be adjusted with respect yto the shell and thesurface of the receptacle, that ,the same intense heat will betransmitted to the 'receptacle from each burner.'

Another object of the invention is to provide a burner nozzle supportedwithin the burner shell and adapted to be adjusted vertically therein.In some instances, the ad 85 justment of the burner nozzle is sufficientto meet the requirements and the rings may not be dispensed with` or bythe use of the rings and adjustment of the nozzle a more intense heatmay be obtained. 0 The invention consists of certain novel features ofconstruction and combination of 'parts which will be hereinafterdescribed and pointed out in the claims: c

A tubular burner shell 10 is-provided with a base having a centralscrew-threaded openj heights.
